Welsh

Welsh pronunciation is illustrated in the characters of Fluellen in Henry V and Evans in The Merry Wives of Windsor. The majority of the distinctive features follow the same trend, but there are some exceptions. There is usually just one localized feature per word.
The most noticeable feature is that voiced consonants (those with vocal cord vibration, such as /b, d, g, v/) lose their voicing.

The representation of the dialect makes great use of distinctive grammatical features, such as the stereotypical discourse tag, look you (H5 III.ii.57). Nouns and the occasional adverb are made plural - conjectures, disparagements, atonements, compromises (MW I.i.28,ff), and peradventures (MW I.i.72).

Grammatical agreement can be non-standard - a joyful resurrections (MW I.i.49). And words are frequently assigned to the wrong part of speech or given the wrong ending.
